A 3-year-old Arizona boy is being hailed as a hero after calling 911 to save the life of his mom when he saw her suffering from a seizure.

Katie Fritzsche, of Mesa, was at home playing board games with her son, Guy, on Sept. 6, when she suddenly started having a seizure. Fritzsche, 38, has a seizure disorder but had not had an episode since 2006.

Guy picked up the family's home phone and dialed the three numbers he knew to call, 9-1-1.

"The next thing I knew I woke up and my house was filled with firefighters and paramedics," Fritzsche told Goodmorningamerica.com. "I said, 'How did you get here?,' and they said, 'Your son called.'"

"I said, 'My son is 3,'" Fritzsche recalled.

Guy had in fact called for help and stayed on the phone with the 911 dispatcher until paramedics arrived. He even knew to lock up the family's dog when the police arrived so that the dog wouldn't bother them.

"My mom is not feeling better," Guy can be heard saying on the 911 calls. "My mom's whole body is wiggling."

Guy, who has overcome his own health problems, including heart surgery at 9-months-old to repair a murmur and both of his heart valves, was one of three citizens honored by the city of Mesa Thursday with a Good Samaritan award.

"He loved it," said Fritzsche, who was hospitalized for a few days after her seizure and is now fine. "He said, 'I'm a hero.'"
